Edmund reveals his plan
In a soliloquy, Edmund confides in the audience that he feels it is unfair to be treated differently from his brother just because his mother was not married to Gloucester, and because he is younger than Edgar. Edmund is determined to change things and manages to fool his father into believing that Edgar is plotting against him. Gloucester calls Edgar ‘Abhorred villain, unnatural, detested, brutish villain – worse than brutish!’
